Question about Home Theater Systems
Continuing our discusion. The issues are as follows:
When I first plug in the system, it clicks with an audible "click-clunk". Then, when I go to cycle the power on, the system will click but the power relay won't latch. I've tried the power-enter button to reset, but doesn't do anything to resolve it. Finally, if I cycle the power button erratically, then sometimes it will latch... sometimes it goes into this endless cycle of clicking about every second... click.... click.....click.....click.....click.
I now have the schematics for the receiver, but where should I begin? Seems to me, it is in the power board (with the transistior,cap and latching relay... but I could be completely wrong.
Any assistance is GREATLY appreciated.
Please confirm 9 volts on Power Board as shown in below picture...
Regarding click-click-click sound of relay its caused by Serial Clock and Serial Data signal failure in digital ICs. Please confirm above signals by using Oscilloscope.
